Title:
RUBBER-MODIFIED STYRENIC RESIN COMPOSITION HAVING HIGH LUSTER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3274491
Kind Code:
B2
Abstract:
PURPOSE: To obtain a rubber-modified styrenic resin composition having extremely improved appearance of molded article, especially luster and excellent impact strength.
CONSTITUTION: In dispersed rubber particles of rubber modified styrenic resin composition, particles of one rubbery polymer having a salami structure are made into particles having small particle diameter and blended with particles having a single occlusion structure. A particle diameter distribution has one peak and the average particle diameter is 0.2-0.8μm. Further the particle diameter distribution is wider than a conventional one and the ratio of 5% value and 95% value of cumulative distribution of particle diameter of volume standard of rubbery polymer particles is 3-45.
